The bolded statement is not true. The SR2 performs better than the XE only at <1000rpm with single fans. At 750rpm push/pull they are already equal.
So, "all-around" the XE is the better rad.

I re-read most 360 rad tests yesterday because I'm making similar choices, and I decided to go with the XE because at my target speeds of around 1100rpm push-pull it will be better, leaving me more headroom if needed to push higher clocks for some benches or such.
The XE has not as many ports, just two on the opposite side of the fittings that can be used for filling, for instance.

The PE instead is a mediocre performer and should be replaced by at least an alphacool x45 or if thicker can fit Nemesis GTX (5.5cm) or SR2 (6cm).

Can't you fit 2x XE 240, or even better one 360 and one 240?
The PE is a bad performer, forget it. Always go for the most radiating area that you can, then for the best rad for your space and usercase (silence or speed).

I am going to say that the better build quality, better port layout and better low noise performance outweighs a very nominal difference in performance if they happen to be in push/pull at over 1300 rpm....which you should be using a GTX for, anyway.

Yeah....the little girl hentai avatar is really creeping me out....

Just keep in mind that all those radiator tests are done in open air setups without filters, mesh, front door, ... in front of the radiator.
1300rpm in a case with filters and a front could, could perform the same as 800rpm in an open air setup.

Which pushes the advantage even further to the rad with better low rpm capabilities.

This is correct
For low speeds, by all means go with the SR2.

I cannot disagree with the build quality but not on the performance.
GTX is a little worse performer, but it's slimmer. At 1300rpm P/P the XE performs much better.

With fans costing more and more these days I'd not even look at push/pull performance.
It's just not worth double the thickness, cost, noise, etc.

Well, I disagree. Having the space for the extra fans, they are wort it, particularly on 50-60mm rads. Noise does not double, it's just a few db more.
We already spend hundreds on custom parts, what are 60 bucks more for a second set of fans?

keep in mind that all the charts are highly subjective. low FPI radiators do well with low RPM fans attached. while high FPI radiators, do poorly with low RPM fans attached, but with high RPM fans of 3000RPM+'s attached to high FPI radiators. these radiators will always out preform low FPI radiators, regardless of what type of fans are attached to the low FPI radiators. the actual design of the radiator does make a difference.


to give a example hardware labs makes a GTR 20 FPI radiator, and with 3000RPM fans attached will out preform all the radiators on that list, except one. the koolance radiator is a 30 FPI radiator, and with 4000RPM fans attached, it will be the radiator at the top of that list.

Tests are subjective now? LOL.
One can extrapolate the data to adapt it to his usercase, and that's it.

very true, that is why I gave a example of what I was trying to explain. as it is a example of information extraction, for several different sources. as the source data sheet you had provided is geared for low FPI radiators only. as this exert from that radiator review clearly states, but the radiator itself only receives a 3.0 score. even though it is the highest preforming radiator he has tested.


https://www.xtremerigs.net/2015/07/3...ator-review/6/


The Koolance HX-CU1020V 360mm is a slim radiator which by default means it will never have outstanding thermal performance. When we break down the results and look at the thermal performance of only the slim radiators, the HX-CU1020 performed very well and ranked second overall for performance. It is however extremely restrictive and this lowered its performance score a bit. However for high speed fans and the ability to dissipate heat in a small space without regard to noise this radiator is simply the best option. No other radiator comes close to such high performance at high airflows.
